IN an incredible move for modern medicine, scientists are using sound waves to help levitate droplets of drugs to make them with less side effects.

In this video, a scientist at the U.S. Department of Energy’s (DOE) Argonne National Laboratory show how they have discovered a way to use sound waves to levitate individual droplets of pharmaceutical solutions.

The acoustic levitator uses two small speakers to generate sound waves at frequencies slightly above the audible range.

When the top and bottom speakers are precisely aligned, they create two sets of sound waves that perfectly interfere with each other, setting up a standing wave.

The acoustic pressure from the sound waves is enough to cancel the effect of gravity, and light objects like droplets from a syringe, are able to levitate when placed there.
